Hi Alan,
You do this even for watchdog0 / for the watchdog we've also registered as
misc_dev. I guess this is intentional and you want the watchdog to be
available as both misc,130 as well as as MAJOR(dog_devt),0 ?
Yes - so that it appears in the watchdog class in sysfs for example.
What happens if one program opens the miscdevice and another program opens the MAJOR(dog_devt),0 device?
I presume that the WDOG_DEV_OPEN status bit will prohibit the opening of the second device in that case...
Correct.

Hans
